1 pk Yeast 1 tb White sugar 12 c Bread flour 12 c Medium rye flour 2 c Whole wheat flour 1/2 c Unprocessed bran flakes 1 tb Caraway seeds 1 ts Salt 1 ts Instant coffee powder 1/4 ts Fennel seeds 1 c Water 2 tb Water 2 tb Molasses 2 tb Cider vinegar 1/2 oz Unsweetened chocolate (I would cut back on that a bit) Cool the mixture to 105-115 degrees and add to dry ingredients. I suspect the exact ingredients don't really matter all that much. As long as the flour-to-liquid proportions are such as to make a dough of good consistency, the result will probably be highly edible.
